Regarding system design most of the new ideas I get are pretty "boring", mostly focusing on constructive methods rather than destructive ones. Anyway, one idea which I kind of like is the following opening structure:
1C = (10)11-14 NT (including 4441 and all 5332) / natural. If natural then extras if two-suited (15-21 if major, 18-21 if diamonds), 11-14 or 18-21 if single-suited.
1D = Strong. 15+ but excluding many strong hands.
1M = 5+ major, unbalanced and less than GF (about 10-21). If single-suited then 11-14 or 18-21.
1NT = Multi. 15-17 NT or weak two in a major.
2C = 10-14, both minors.
2D = 10-14, 6+ diamonds.
2M = 10-14, 4M and 5+ minor.
2NT = Not quite sure yet. Perhaps 6+ clubs and 4 diamonds.
Much inspiration is taken from Ulf Nilsson's (ulven) system design. The idea is to have natural bidding with most unbalanced hands, even when strong (especially so strong two-suited hands). I'm considering if all single-suited 15+ hands should be included 1D, but I haven't decided. The two-level opening bids are hands which usually open 1m, and now they're much tougher to bid against (but also harder to have a constructive auction, ofcourse). What I'm aiming for is:
- Using the natural system as a base, but removing some awkward hands (especially for the minors).
- Having a less overloaded nebulous minor opening, compared to systems like strong club (most of them) and 5542.
- Having less hands in the strong minor, compared with strong club, which hopefully makes competitive auctions easier.
The hands included into 1D are:
- 18+ NT.
- 15+ with diamonds as the longest suit.
- 15-17 single-suiters (maybe 15+, haven't quite decided).
- 15-17 with 5C and 4D (could perhaps be included in 1C, but these hands can be hard to bid in the natural system).
- Any GF.
Using the 1NT opening as "multi" is probably a bad idea, but I've been wanting to try it and saw this as an opportunity
